沈下を矯正するものである。(Function) As described above, when laying a pipe on a reinforced concrete foundation, the present invention interposes air bladders at predetermined intervals between the bottom surface of the pipe and the foundation, and A cushioning material is mounted on the pipe, and when uneven settlement occurs, pressurized fluid is injected into the air sac from within the manhole to inflate the air sac and lift the culvert to the appropriate position. The uneven settlement of the pipe is corrected by filling the void created between the pipe and the foundation with filler and hardening it in the same manner as the pressurized injection of pressurized fluid into the air bladder. It is something to do.

け圧縮変形した状態で管渠１が扛上される。 1 is a reinforced concrete pipe, and when it is laid on a reinforced concrete foundation 2, reinforced rubber or the like is installed between the pipe seating part 2a with an arcuate cross section provided on the upper surface of the foundation 2 and the lower surface of the pipe 1. The constructed pressure-resistant air bladders 3 are interposed at predetermined intervals, and a cushioning material 4 such as styrene foam is placed on the upper surface of the pipe conduit 1. (See Figure 1) If uneven settlement occurs in the pipe culvert 1,
As shown in FIG. 2, pressurized fluid is sealed through injection pipes (not shown) that are buried underground in advance and are connected at one end to each air bladder 3 and at the other end to a manhole (not shown). When the air sac 3 is inflated and the pipe 1 is lifted up, the pipe 1 is lifted with the cushioning material 4 mounted on the upper surface of the pipe 1 compressed and deformed by δ.

１の不同沈下を矯正するものである。 In this way, each pipe 1 is lifted up by the air bag 3 so that it is located on the same line as when it was laid, and in this state, the pipe is injected from inside the manhole via the injection pipe in the same manner as when filling the pressure fluid. Below the ditch 1 and the foundation 2
The uneven settling of the pipe 1 is corrected by injecting and solidifying a liquid filler such as synthetic resin cement between the pipe seat 2a and the pipe 1.

渠１の破損を防止しうるものである。 Generally, the area around the pipe culvert 1 is backfilled with soil or sand, and this soil or sand acts as a wall, and all the earth pressure on the upper part of the pipe culvert 1 is concentrated as a load, causing the pipe 1 to break. However, according to this embodiment, the cushioning material 4 is mounted on the top surface of the pipe culvert 1, so when the pipe culvert 1 is lifted up as described above, the compression of the buffer material 4 The deformation buffers the earth pressure above the pipe culvert 1 and prevents the pipe pipe 1 from breaking. In addition, after the correction work, the air sac 3 can be once deflated and reused, and when backfilling the pipe culvert 1,
By inflating the air sac 3 to a certain extent, it can resist the additional earth pressure that momentarily exerts a large amount on the pipe culvert 1, thereby preventing damage to the pipe culvert 1 due to the added earth pressure during backfilling work. It's watery.

下の矯正が可能である。 In addition, if uneven settlement of the pipe body is predicted in each construction method such as shield, mini-shield, and propulsion method, it should be noted that if uneven settlement is expected, it should be treated by a method such as attaching an air bladder to the face or the lower part of the pipe in advance. Therefore, it is possible to correct uneven settlement.
